What is nuclear fusion?Nuclear fusion produces energy by fusing atoms together. Atomic cores (nuclei) merge together to form a heavier—though unstable—nucleus, releasing mass to regain stability. This mass release corresponds to an energy release, given Einstein's equation E=mc2, which says in part that mass and energy can be converted into each other. The sun, along with all other stars, uses nuclear fusion to generate energy, which is released as heat and light. The 2022 Fusion Breakthrough In late 2022, scientists led by Dr. Annie Kritcher at the Lawrence Livermore National Laboratory (LLNL) briefly replicated the power of the sun. Replicating the sun's power requires replicating the extreme heat and density conditions within the sun's core. Atomic cores are positively charged, meaning they repel each other. To overcome this barrier, scientists need to apply massive amounts of heat and keep atomic cores extremely close together. For the first time, scientists produced more energy from fusion than the amount of energy it took to maintain these conditions. Fusion is a greenhouse-gas-free source of potentially unlimited electricity, powered by hydrogen we can take from water, and creating no long-lived radioactive waste. According to the International Atomic Energy Agency, fusion generates four times more energy per kilogram than the fission used for powering nuclear plants, and nearly 4 million times more energy than burning fossil fuels for energy. What's Next?Commercial nuclear fusion is still a long way off. While the physics aspect of fusion is “solved,” fusion remains a complicated engineering problem. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory has the most powerful laser in the world to blast heat at atoms, but it is the size of three football stadiums, very old, slow, inefficient, and clunky. There are still unanswered questions, such as how to affordably capture fusion energy, and how to keep a fusion reaction going for a long period of time. And although the laser shots at the NIF were weaker than its fusion output, the amount of energy drawn from the grid to create those lasers is 120 times more than the fusion output generated at LLNL. About Dr. Annie KritcherDr. Annie Kritcher is a nuclear engineer and physicist at the National Ignition Facility at Lawrence Livermore National Laboratory Weapons and Complex Integration's Design Physics Division. She led the recent nuclear fusion breakthrough at LLNL. In 2022, Kritcher was elected fellow of the American Physical Society. She earned her PhD at UC Berkeley. Further ReadingA shot for the ages: Fusion ignition breakthrough hailed as ‘one of the most impressive scientific feats of the 21st century' | Lawrence Livermore National LaboratoryUK Power Grid Could Have First Commercial Fusion Reactor By 2030sWorld's largest nuclear fusion reactor promises clean energy, but the challenges are huge - ABC NewsAnnie Kritcher leads revolutionary nuclear fusion experimentIAEA, What is nuclear fusion?NOVA Now Universe Revealed Podcast, Can We Recreate the Power of Stars Down on Earth?

Many of our local law enforcement officials have expressed concerns about a set of new laws (HB 1310, HB 1054) that, among other things, require stricter standards for probable cause when detaining someone, require de-escalation during encounters, ban chokeholds and significantly restrict the use of tear gas. Despite the handwringing, it seems pretty reasonable to us, so we spoke with Enoka Herat of the ACLU Washington about what the laws do and don’t do Further readingA good primer from Crosscut about what police are allowed and not allowed to do under the law.A good primer on carotid and choke holds in the Washington Post, and why 62% of the largest police forces in America banned them unilaterally … you know, rather than being forced to by their state legislature.—Note: early in the episode Luke calls himself lugubrious when he obviously — OBVIOUSLY — meant loquacious.

Phil Haunschild joins us this week to discuss how blockchain technology could potentially eliminate the governments’ presence in welfare and charity.Among the uninitiated, ‘blockchain’ is often treated as a synonym for ‘cryptocurrency.’ But blockchain technology has many other potential applications, including ways of improving the efficiency and transparency of good governance. For example, Phil Haunschild from the Idaho Freedom Foundation explains how a state-level blockchain could replace the expensive requirement to post public notices in newspapers, potentially saving millions of dollars in just one state. Phil then outlines his even grander plan to replace food stamps and other welfare programs with privately-run, blockchain-enabled charities.How is blockchain a better tool than a state-run database? How do smart contracts work in tandem with blockchain technology? Could blockchain be used in order to eliminate the presence of government in welfare and charity?Further ReadingA path to eliminate government subsidies for the media, writted by Phil HaunschildIdaho Freedom Foundation project proposal about how blockchain could allow people to be in control of the welfare system rather than the government.
